strange quark

strange quark

n. Abbr. s

A quark with a charge of - ¹/₃ , a mass about 400 times that of the electron, and a strangeness of -1. See Table at subatomic particle.

strange quark

A quark with an electric charge of -1/3 and a mass of 391 electron masses, greater than that of the up quark and down quark, but smaller than that of other quarks. The presence of a strange quark contributes strangeness of -1 to the physical system containing it, while a strange antiquark contributes strangeness of +1. See Table at subatomic particle.

strange quark - a quark with an electric charge of -1/3 and a mass 988 times that of an electron and a strangeness of -1 squark quark - (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3; "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"
